If you discussed your plans with the the guys at Lentech, then you should be alright. If anybody knows the AOD, its those guys (I've got one too). But the stall converter behavior is really dependent on the application. A 2800 stall converter will work differently on your 5.0l motor than the same converter will on a monster 460 big-block. How, when and where your torque appears is the big driver.
If you told Len what you were planning you'll be OK. Even without any dyno curves from your motor/car, they've got a good idea of what the torque curve will look like and what/where the peak will be. That along with your basic information should be enough.
